High-pressure cylinders for argon, oxygen, nitrogen, helium, hydrogen and ARCAL premium shielding gases for our welding applications are available in sizes from 20 cubic feet to over 300 cubic feet. While the C25 is more expensive than the 100 percent CO2, it is less expensive . Spedgas bottles are refillable and work on a swap and go system. In most applications, this will create a pleasantly smooth weld and keep the amount of spatter to a minimum. Metal Inert Gas (MIG) welding is an arc welding process that uses a continuous solid wire electrode heated and fed into the weld pool from a welding gun. Flux core welding enables the welders to weld without the need to use any type of gas for any kind of metals. However, we get into trouble because you can make welds look good regardless of what gas you use, for the most part. Hydrogen Hydrogen is used as a shielding gas when mixed with other shielding gases such as argon. If you want a "one-size-fits-all" option, a MIG welding shielding gas with a 75/25 mix of argon and CO2 is likely going to be your best bet.
